2. a). A pure substance turns out to have a vapor pressure of 1 bar at 125°C. Using the Causius 25°C, knowing that its molar enthalpy of vaporization is 46.0 kJ.mol and can be considered Clapeyron (or inexact Clapeyron) equation, calculate the vapor pressure of that substance at constant over that temperature range. (10 pts.) If you are unable to make this evaluation, for partial credit, explain whether you expect the vapor pressure at 25°C to be higher or lower than 1 bar and why.
